suspend/resume panic in ACPI..

With all the trouble in suspend/resume lately I thought to better test 
it out on my trusty workstation that always has worked with 
suspend/resume (modulus various problems in our ACPI code from time to 
time) and now it just panic's as seen below.

Something is not koscher in there, and that need to be fixed before we 
can call 5.3 stable IMHO...


in single use mode:
#acpiconf -s3
panic: pmap_invalidate_page: interrupts disabled
cpuid=0;
KDB: enter: panic
